iphone 14 pro was charging overnight and when i woke up it was hot and not turning on

I plugged in my phone last night and let it charge like I normally do. I checked after about 2 hours and it was at 80% but I decided to keep it plugged in since I wanted it at full charge. When I woke up, I was about 2 hours past when I was supposed to and I checked my phone and it wouldnt turn on. There is a black screen and holding down the button isnt working. I am currently letting it cool down before I try again, but what do I do?
